uponcelluloid or the. like foundation con-v tainin' Intro-cellulose. I Ce uloidtypically of various cellulosic or pyroxyli'n compounds that are marketed under diflerent names-although it has may desirable qualities and is used in making many articles that might well be the foundation for artists. decorative edorts, does not lend itself to such work because of the difficulty in securing permanency in the ornamentation. For instance, hand paintingon celluloid with' ordinary painting materials, such as oil paints, varnishes, etc., is practised but little for the reason that the applied ornamentation so readily scales or chips 0d and becomes easily soiled that it cannot be. regarded as permanent or satisfactory. Solutions of cellulosic materials:

have been employed as paint for decorating purposes, particularly for uniform or plain itints on various foundations as wood, metal,

etc, and when so used theyhavethe important advantage of superior-permanency on the article on which it is applied. Thus pyroxylin enameling for coatlng extensive flat 'or plain surfaces of wood-or metal is 'well known, Such cellulosic solutions are su'cient tenacity for subsequent treatment,

not fnuch used, however, for artists decorative purposes as they are really impractical because of their numerous disadvantages,

Among theseis-the fact that the rapid drying of thesolution greatly limits the artlsts ration, as a skin-'dries on the brush before it can be applied tothe foundatlon.

Special ob]ects of my'inventlonftherefore, are to provide a suitable decoratln palnt havinga soluble cellulosic or yroxy in base and a suitable pigmentation, in a form con venient for commercial sale andfor facile application in the artistsworkiand further to provide a method for,fix 1ng or rendering permanent the ornamentatmn applied wlth such paint. o

form convenient for application with (a.

brush, the artistic ornamentation ofsuitable foundations, (and especially for the practice of my celluloid-ornamenting method) I provide a mixture or paint, preferably in a thick creamy or pasteconsistency, composed of a soluble cellulosic base, a suitable pigment to give the desired color or tint, and a llquid which is not a solvent for the base and preferably not a solvent for the pigment, the liquid vehicle being of a volatile character i The particular ingredients employed may be widely varied but typically pyroxylin as the soluble-cellulose base material, amineral pigment, such as a suitable metaloxid, suld, chromate, or the like, and Water as a volatile carrying agent inert with'respect to the solid base and pigment materials may be employed. Also the preparation of the paint may be variously carried out and the primary or pigmented material marketed in diderent forms, For instance, the two solid ingredients may be ground dry together and sold in that form for admixture with water, benzin, or other suitable carrying agent,

the artist; or they may be ground in thev carrying agent and dried for sale in powf packaged as a semi-liquid. It will be understood dered' form, or ground in the liquid {and a that at alpha;

ment of the inert carrying liquid-is pr i;- it marily intended merely to give a proper consistency such that the undissolv'ed ingredients may be worked most edectively by the artists andebrush-applied to the foundation with the greatest ease: ,Urnamentation thus applied adheres to the foundation, when the'volatile carrying agent evaporates with' .as hereinafter set forth, but diiesnot have the-attributes necessary to real permanency g of ornamentation.

Subsequently to this temporary appli cation,so to speak-of the primary plg-v mented material to the foundation and the,

evaporation of the carrying agent-therefrom, the ornamentation is lined by the application thereto of a g agent-which is a solvent for the soluble cellulosic base material but, preferably,is not a solvent for the m ent. Thus, pursuing the example heretoore given the decorations alcohol and ether which elves the soluble cellulosic content andthis fixing agent, permeating the decorative coating, also attacks the celluloid. foundation, but without dissolving the pigment, and so merges the cellulosic substances of the base and the paint,

homogeneously bonding the paint to the celluloid foundation and giving to the finished.

decoration a most satisfactory permanency of outline and color.

Where a fixing agent is employed that consists of the solvent for the cellulosic material alone, its tendency is .to give what is known as a mat finish, if the cellulosic content with the pigment is low, but where a higher gloss finish is desired, the degree of glossmay selectively be regulated by the artist by using a solvent that has had incorporated with it more or less pyroxylin that is deposited as a surface gloss upon the evaporation of the solvent.

It will be understood that while, as herein before suggested, the use of colors having a cellulosic base is particularly desirable for,

the ornamentation of celluloid foundations, the same method above described may be used in applying ornamentation to foundations of other materials such, for instance, as glass, wood, metal,etc., but of course under 7 such circumstances the fixed ornamentation,

although it adheresstrongly to the foundation surface, is not homogeneously bonded to the foundation as it is to celluloid.

It will further be understood that while for commercial purposesfit is generally preferable that neither of the liquids employedthe carrying agent or the fixing agentshall be a solvent for the pigment, the principal reason for such a selection of liquid is to prevent running of differently tinted pigments together; but in some rarer instances it may be desirable to employ colors that will run together under the-fixing treatment, and

" this may be accomplished, for one-exam le,

by using a suitable'pigment, ,such as amlin coloring, which is soluble in the fixing solution.

While I have herein described in some de- -tail particulars of a desired practice of my invention it will be understood that I do not limit myself to such details in the broader aspect of my invention and that many variations from the specific illustrations herein given may be made without departure from the spirit of my invention,

v within the scope of the appended clalms.

Having described my invention, what I claim is i 1. The art of fine art painting on a celluloid or the like foundations containing nitro- .consistsin painting on a celluloid or the like foundation containing nitro-cellulosc with a paint comprising a 'soluble cellulosic material, a pigment, and a volatile liquid that is not a solvent for the base material, permitting said liquid to substantially evaporate and thereafter treating the deposited paint material with a volatile liquid that is a solvent for said soluble base material.

3. The art of fine-art painting upon a celluloid or the like foundation containing nitro-cellulose which consists in applying to the foundation a paint having a soluble cellulosic base in non-dissolved condition and subsequently applying a volatile solvent for the cellulosic base and celluloid foundation.

4. The art.of fine-art painting upon a celluloid orthe-like foundation containing nitrocellulose which consists in applying to the foundation a paint, comprising a soluble cellulosicmaterial, a color pigment and a volatile liquid that is not a solvent for the soluble'cellulosic material, subsequently applying thereover a volatile liquid that is a sol.-

vent for the cellulosic material and foundation, but not a solvent for the pigment.

5.. The art of fine-art painting upon a celluloid or the like found atlon containing nitrocellulose which consists in applying to the foundation a paint comprising a soluble, cellulosic material, a color pigment and a vola- In testimony whereof I hereunto set my hand.
